I really don't think packaging is a sore spot for Linux, it's actually the other way around, it as plenty fantastic solutions, for that and for distribution of the packages, superior to the alternatives of more used OS.

This obviously doesn't mean that there are no issues with package formats, there are, but they are still better than anything else that is default on others, and what others have been doing is to imitate Linux to improve.

The point on confusion I agree.

The sandbox of a flatpak is the same on all distributions, unlike a snap¹. In addition, the snapcraft.io backend is proprietary (unlike Flathub), so this format will never be adopted by all distributions. If they really want to be cross-platform, they should start by working on these two points.

apt-get install firefox is the main reason for me for stay away from ubuntu and never, ever use their server flavour.

They should keep both things, native applications and snap clearly separated instead of silently inject snap packages in apt.

Thats simply evil.
